Marine diesel engine forging is an important part of Marine power system, and its manufacturing technology has an important impact on the performance and reliability of diesel engine. This paper introduces the manufacturing technology and development trend of Marine diesel engine forgings.
Manufacturing technology of Marine diesel engine forgings
Free forging
Free forging is a traditional forging method in which the blank is struck or pressed to form the desired shape and size by using tools such as free forging hammer and anvil iron. Free forging has high flexibility and can produce more complex shapes and structures. However, the efficiency of free forging is low, and it is more difficult to produce large and heavy forgings.
Model forging
Model forging is a forging method that forms according to a model. A model with the same shape and size as the final product is first manufactured, and then the blank is placed in the model and pressed or impacted to form the same shape and size as the model. The high precision of model forging is suitable for the production of large and heavy forgings. However, the manufacturing cycle of model forging is longer and the cost is higher.
Precision forging
Precision forging is a forging method that uses high-precision mold and advanced technology to form. Through the use of high-precision molds and precision machining equipment, precise shaping and dimensional control of the billets can be achieved. Precision forging has high accuracy and stability, suitable for the production of small and precision forgings. However, the equipment and process technology of precision forging have higher requirements and higher costs.
Development trend of Marine diesel engine forging manufacturing technology
The application of digital manufacturing technology
Digital manufacturing technology is a method of manufacturing using computer technology. Through the use of computer-aided design (CAD) and computer-aided manufacturing (CAM) and other technologies, the whole process of digital management and control from design to manufacturing can be realized. Digital manufacturing technology can improve manufacturing accuracy and efficiency, and reduce manufacturing costs and risks.
Application of intelligent manufacturing technology
Intelligent manufacturing technology is a method of manufacturing using robots and automated equipment. Through the use of robots and automation equipment, the automation and intelligent control of the production process can be achieved. Intelligent manufacturing technology can improve production efficiency and product quality, reduce labor costs and human factors.
Application of green manufacturing technology
Green manufacturing technology is a manufacturing method that considers environmental impact and resource utilization. By using environmentally friendly materials and process technologies, the environmental impact of the manufacturing process can be reduced. At the same time, by optimizing the design and manufacturing process, the efficiency of resource utilization can be improved. Green manufacturing technology can improve the competitiveness of enterprises and meet the requirements of sustainable development.
The development of custom manufacturing
With the diversified development of Marine power system, the demand for Marine diesel engine forgings has also shown a trend of customization. In order to meet the needs of different customers, manufacturers need to have the ability to provide personalized customized services. Through the use of advanced production technology and highly flexible production lines, small batch, multi-variety production mode can be achieved to improve the differentiated competitiveness of products.
Improvement of quality control and assurance system
Quality is the lifeblood of Marine diesel engine forging manufacturers. In order to ensure the consistency and reliability of product quality, manufacturers need to continuously improve the quality control and assurance system. Through the use of advanced testing equipment and scientific testing methods, the key links in the production process are strictly checked, and the collection and analysis of quality data are strengthened to achieve the whole process monitoring and management of product quality.
The manufacturing technology of Marine diesel engine forgings is developing in the direction of digitization, intelligence, green and customization. Manufacturers need to keep up with The Times, actively introduce advanced production technologies and processes, optimize production processes and management systems, in order to improve product quality, reduce costs, improve efficiency and meet customer needs. At the same time, manufacturers also need to pay attention to environmental protection and sustainable development in order to achieve win-win economic and social benefits.
